Definitions

  • ABSTRACT An assembly for joumalling spindle shafts in spinning and twisting machines. At least one resilient elongated member, such as a bar spring interconnects the neck and foot bearing. The neck and foot bearing are secured firmly to the respective ends of the resilient member.
  • the present invention relates to apparatus for journalling the spindle of spinning frames and twisting frames.
  • the spindle of a conventional spinning and twisting frame is journalled in a housing or bolster by a radial neck bearing surrounding its upper portion and a foot bearing axially supporting its lower end. It is the primary object of the present invention to provide an elastic yieldable connection between the neck and foot bearings so that the operating and running characteristics of the spindle are greatly improved and a more quiet and smooth operation is obtained.
  • the present invention has as its object the provision of a journal for a spindle in a spinning and/or twisting frame wherein the neck and foot step bearings may be yieldably connected with each other and/or yieldably connected with the spindle housing or bolster.
  • apparatus for journalling the spindle of a spinning and/or twisting frame wherein the neck bearing and the foot bearing are connected by at least one bar spring.
  • the bar spring is connected at one end to the neck bearing and at the other end to the foot step bearing and preferably extends parallel to the axis of the spindle.
  • the bar springs are held in a position between the neck and foot step bearings in a collar or a holder which is secured at its outer periphery on the inner wall of the spindle housing or bolster.
  • the neck and foot step bearings are yieldably movable with respect to each other as well as with respect to a fixed position on the bolster itself.
  • FIG. 1 is a longitudinal section through a spindle bolster showing the connection of the neck and foot step bearings in accordance with the present invention
  • FIG. 1a is a top plan view of the foot bearing
  • FIG. 2 is a detailed view of an assembly of neck and foot step bearing with a plurality of bar spring connection means, FIG. 2 being broken and showing portions in section,
  • FIG. 2a is a top plan view of the foot bearing
  • FIG. 3 is a sectional view similar to that of FIG. 1 showing still another embodiment of the present invention
  • FIG. 4 is a sectional view taken along line 44 of FIG. 3.
  • a spindle bearing housing or bolster l of conventional design is seen in FIG. 1.
  • the bolster is adapted to sit within a hole formed in a spindle bank with its radial flange 2 resting on the upper surface of the bank.
  • the bolster is secured by a nut screwed beneath the spindle bank on its exterior threaded surface 3.
  • the bolster is closed at its lower end and has press fit or similarly secured at its upper end a plug-like insert 4 in the top of which is secured a neck bearing 5 comprising a conventional radial roller bearing of the type commonly employed in similar spindle arrangements. Extending through the neck bearing 5, the insert 4 and the bolster l is the shaft 6 of a conventional spindle.
  • the lower end of the spindle shaft 6 rests within an axial foot step bearing 7 which may also be of conventional construction.
  • the neck 3 bearing 5 and the foot bearing 7 are connected by a bar spring 8 which extends parallel to the shaft 6 and which is fastened at each end in the neck and foot step bearing respectively.
  • the insert 4 is provided with a blind bore 9 into which the bar 8 is press fit.
  • the end of the bar may be provided with riflings or splines 10 so that it more securely fits within the blind bore 9.
  • the foot bearing 7 is provided with a through bore 7' through which the lower end of the bar spring 8 extends to a point beyond the lower face 11 of the foot step bearing 7.
  • This lower end of the bar 8 is formed with a flanged head 12 which secures the bar in place.
  • the diameter and the material of the bar 8 are so chosen that the axially extending bar, parallel to the spindle shaft 6, produces a yielding bias between the foot bearing 7 and. the neck bearing 5 so that a smooth and quiet running of the spindle and a resiliently yieldable bearing apparatus for the spindle is obtained.
  • a conventional damping coil 13 surrounds the foot bearing 7 between it and the inner wall of the bolster 1.
  • the damping coil 13 comprises a helical member extending from the lower end of the bolster axially along the inner wall thereof and is secured in its position by a split ring 14 or similar spring-like nut seated in an annular groove formedin the inner wall of the bolster.
  • the nut 14 prevents axial movement of the helix with respect to the bolster.
  • FIG. 2 an assembly of a neck and foot step bearing connected by means of the plurality of yieldably resilient rod-like spring members is shown without refer-. ence or connection to the bolster or bearing housing.
  • a neck bearing 50 and a foot step bearing 70 are yieldably connected relative to each other by a plurality of bar springs 80 which are secured at their upper ends in a slotted opening 15 formed in the end of the neck bearing insert 40.
  • the bar springs can be secured in the opening 15 by filling the openings with solder material, lead or the like.
  • the opening 15 may be mechanically deformed along its edges so that the material is upset to hold and grasp the ends of the bar spring securely.
  • each of the bar springs 80 are securely held in a sleeve 16 in which the foot bearing 70 is secured.
  • the sleeve 16 is provided with a series of blind holes 17 into each of which the end of a bar spring 80 is inserted.
  • the lower end of the bar springs 18 may be rifled or splined and press fit into the blind bores 17 in the manner described in connection with the embodiment of FIG. 1. Further,
  • each of the bar springs 80 is slightly smaller in diameter than the rest of the bar so that a shoulder is provided which when placed against the frontal edge 18 of the sleeve 16 provides a predefined and fixed position for the bar spring.
  • the lengths of the bar springs may be fixed so that they are uniform with each other.
  • the yieldable resilient connection between the neck and foot step bearing is formed by a plurality of uniformly spaced bar springs lying in a circular path coaxially about the spindle axis.
  • Each of the bar springs 80 has a circular cross section.
  • the number of bar springs can be varied from those shown in FIG. 2 and the bars may also be arranged nonuniformly spaced from each other and in other than a circular orbit about the spindle.
  • they may have a cross section other than a circular rod.
  • the assembly of FIG. 2 can also be made with one bar spring as shown in FIG. 1.
  • the assembly shown in FIG. 2 comprises a unitary whole which can be pre-assembled and stored and transported in this condition. It may thus be easily in and is axially seated on a foot step bearing 170.
  • the I neck bearing 160 and the foot bearing 170 areconnected by three bar springs 180, 180 and 180". These bar springs are secured at their upper end in slots formed in the neck bearing insert 140.
  • the securement of this upper end of the barsprings can be made in such a manner as that described in connection with the earlier embodiment by filling the slot with solder or similar material or by deforming the edges of the slotted portion of the insert 140.
  • the lower end of each of the bars 180, 180' and 180" aresecured in a similar manner in slots 116 formed in the foot bearing 170. Both ends of the bar may be splined or rifled to assist in its securemerit.
  • the bars 180, 180 and 180" are held in an annular supporting collar 119.
  • the collar 119 has a plurality of axially extending holes 120, 120 and 120" conforming I to the number of bar springs 180, which extend parallel to its central axis.
  • the holes are formed by slotting the collar 119 radially from its peripheral edge so that the spring bars 180 may be inserted therein and maintained or other material to hold the bar spring or may be physi I ically deformed and upset so as to crimp the bar spring within the axial journal 120, as indicated in FIG. 4.
  • the bar springs 180 are held within the holes 120 so that they maintain an axially parallel and uniformly spaced arrangement with respect to the axis of the spindle shaft 6.
  • the central bore 121 of the annular collar 119 has a diameter which is slightly greater than the diameter of the spindle shaft 6 so that a degree of radial play is provided.
  • the outer diameter of the collar 119 is somewhat larger than the neck bearing insert and the foot bearing so that it fits tightly within the inner diameter of the bolster and is securely press fit in place so that it is fixed against movement relative to the bolster.
  • the degree of elasticity of the connection between the bearings and between the bearings and the bolster is adjustable and determinable within limits and can be easily matched to the desired requirements, withoutdeparting from the basic structure as shown.
  • the material, the dimensions of the bar springs as well as the number of bar springs can be varied and can be determined to provide the desired degree of yield.
  • the three bar springs shown in FIGS. 3 and 4 may bereplaced with any number of bar springs as for example the number shown in the embodiment of FIG. 2.
  • the relative distance between the neck and foot bearings with respect to the collar 119 can also be varied. As seen in FIG. 3 the distance between the collar 119 and the neck bearing is less thanthe distance between the collar "119 and the foot bearing.
  • the collar 119 By arranging the collar 119 in this off cen- 1 tered position, a greater degree of elasticity is provided for the foot bearing 170 than for the neck bearing 150.
  • the relative degree of yield By predetermining the position of the collar 119 along the length of the bar springs the relative degree of yield can be determined. This variable degree of yield or elasticity can be obtained even with a central positioning of the collar 119 or even with an off center arrangement the degree of elasticity can be further varied, by making the portion of the bar spring between the collar 119 and the foot bearing 170 of a different dimension than the portion between the collar 119 and the neck bearing 150. In this way the bar springs above and below the collar will have a different degree of oscilla tion and resonance as well as a different degree of radial and axial elasticity.
  • Still another way of making the yield different is to arrange a different number of bar springs between the collar and the foot bearing as between the collar and the neck bearing. This also provides a relatively different spring constant above and below the collar. It is also possible, that instead of connecting the neck to the foot bearing, the collar 119 is connected to only one of the bearings. Similarly, two
  • collars may be used each connected to their respective bearing.
  • degree of elasticity or spring yield can be modified or varied further by employing a bar of different configuration than that shown in the drawings.
  • a conical, square, oval or other sectional form can be used rather than the circular sectional profile indicated.
  • the elastic effect of the bar springs can be augmented by the use of conventional and well known damping means.
  • the foot bearing 170 is surrounded by an oil-damping helical coil 113 which extends axially from the bottom of the bolster 101 into contact with the lower surface of the collar 119.
  • an additional damping coil 114 (seen on the right half of 140.
  • the closure ring 117 is made of such an elastic material that it seats against the upper end of the bolster 101 and closes its interior so as to prevent the escape of lubricant and/or damping oil without interfering with the radial movement of the insert 140.
  • the closure ring 117 also fixes the second damping coil 1 14 against axial movement.
  • the collar 119 is press fit securely within the interior of the bolster 101. It can however be placed in its desired position by forming a shallow re cess within the inner surface of the bolster or by providing the bolster with at least one rim or edge against which the piece 119 can be seated.
  • the damping coils 113 and 114 can be varied in their effect by modifying their structural form, that is by selecting the strength of the material forming the coil or by selecting the number of windings into whichthe coil is turned. Different damping values may be employed for each of the neck or foot bearing ends respectively. Different damping means may also be employed for each .of the neck and foot bearings.
  • the .foot bearing 170 can be surrounded by an oil damping coil 113 as shown in the drawing, while the bearing insert can employ a damping sleeve 123 (indicated on the left side of FIG, 3
  • the damping sleeve 123 may be made of an elastic material such as rubber, synthetic rubber or, synthetic plastics.
  • Such a damping sleeve does not require oil or other lubricant and thus the upper portion of the bolster 101 does not need to have such material supplied; to it nor is it required to form an oil reservoir.
  • the present invention provides a simple elastic and yieldable spring-like connection and damping arrangement between the neck and foot bearing.
  • the bar springs enable the maintenance of the neck and foot bearings in a pre-defined axial distance from .each other but permit their freedom of radial movebolster or the spindle bank by which noise maybe i transmitted.
  • the neck bearing is surrounded by an elastic sleeve or ring 122 which is interposed between the bearing andthe wall of the carrier insert 140.
  • the material from which the ring 122 is made may be rubber or similar dampening material and may be secured as by gluing to the inner wall of the insert 140.
  • An assembly for joumalling the shaft of a the spindle of a spinning and twisting frame comprising a bearing housing having a neck bearing at the upper end and a foot bearing at the lower end, each of said neck and foot bearing being mounted in a bearing mount located within said housing, at least one of said neck and foot bearing mounts being axially movable with respect to said housing and at least one elongated tension spring fixedly connected at its respective ends to said neck and foot bearing mounts so as to yieldably space said neck and foot bearings from each other.
  • damping means interposed between said housing and at least one of said neck and foot bearings.
